THREAD-CUTTER.

Specification of Letters Patent.

Patented Apr. 6, 1915.

Application filed October 1, 1913. Serial No. 792,832.

To all whom it may concern:

Beit known that I, ALMA NIEBERG, a citizen of the United States,residing at Brooklyn, in the county of Kings and State of New York, haveinvented new and useful Improvements in Thread-Cutters, of which thefollowing is a specification.

This invention relates to sewing accessories, and it has particularreference to a simple and improved thread cutting device which willobviate the use of scissors for the purpose of cutting thread, sewingsilk and the like, thus saving time and energy.

A further object of the invention is to produce a simple and efficientdevice capable of being utilized as a weight to hold light articles,such as paper patterns, pieces of dress material and the like in place,but which also serves as a casing and support for a thread cuttingblade.

A further object of the invention is to combine the blade with the basein such a fashion that the sharp edge of the blade shall not be exposedexcept when desired for use, the construction being such that the bladewill be guarded when the device is not in use, thereby preventing injuryto the blade and danger of incurring accidental cuts.

With these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claims.

In the accompanying drawing has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawing,Figure 1 is a perspective view showing a preferred formof the invention, and showing the cutting blade exposed in position foruse. Fig. 2 is a top plan view of the same. Fig. 3 is a sectional detailview taken on the line 3-3 in Fig. 2. Fig. 4: is a sectional detail viewtaken on the line 44 in Fig. 2.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The base 15 of the improved device con sists of a block of wood, metalor other material or combination of materials of a specific gravitysufficiently high to enable it to be utilized as a weight. This block orbase member may be of any convenient shape; in the drawings anapproximately cylindrical block has been shown.

Fitted in the block or base 15 and extending partway across the same ina diametrical position is a blade 16 having a sharp cutting edge 17. Topor cover members 18 are provided with recesses 19 to receive the bladewhich latter has been shown as being provided with slots 20 for thepassage of transverse pins 21, whereby the members 18 are assembledslidably therewith. Each of the members 18 is provided with a notch 22in the upper side thereof, affording a thumb grip, enabling said membersto be conveniently manipulated; one of the members is also provided witha resilient socket 23 to receive a stud 24 carried by the mating memberand affording a spring clasp or connection, similar to an ordinary gloveclasp, whereby the slidable members may be connected together when movedto a projecting position with respect to the blade so as to expose thelatter. The slidable members 18 may be constructed of materials thatwill enable them to be utilized as pin cushions if so desired.

It will be seen that by moving the members 18 in opposite directionsapart from each other the blade 16 will be uncovered, thus enabling itto be utilized for cutting thread and the like. When it is not desiredto expose the blade for present use, the members lS may be moved towardeach other and secured together by the interengaging snap members 23,24. The device will then present the appearance. of an ordinary pincushion and may be utilized as such.

It will be understood that while I have shown and described specificforms of my invention, other modifications may be resorted to within thescope of the appended claims.

Having thus described the invention, what is claimed as new, is

1. A device of the class described comprising a relatively heavy baseblock, a sharpedged blade projecting upwardly from the top face thereof,said blade having longitudinal slots, and cover members having bladeengaging recesses, said cover members having pins extending transverselytherethrough and slidably engaging the slots in the blade.

2. A device of the class described comprising a relatively heavy baseblock, a sharpedged blade projecting upwardly from the top face thereof,said blade having longitudinal slots, and cover members having bladeengaging recesses, said cover members having pins extending transverselytherethrough and slidably engaging the slots in the blade, and saidcover members being provided on their opposed faces With interengagingfastening members.

In testimony whereof I aiiiX my signature )5 in presence of twoWitnesses.
